Amy,
I'm going to go out on a
big limb here and do exactly what you
asked of us in the first place... Critiques on the
photography, and not the "conservation issues"...I am not a professional photographer, but I have done lots of cave, nature and portrait photography, so here's what I see.....
Photo #1:
Not enough lighting on yourself..... I'm sure you
had your helmet with you, so next time, try using the light(s) from it to help with some front lighting. It looks as though you are trying to get that "looking at the formation" shot, but your face isn't visible to portray the idea of the shot. It also detracts from the "corset and cave" concept, if I can't actually
see the corset.
Also, the flash burst is too visible.
Good idea, photographically, but the shot is terribly hampered by lighting issues...(which I know you are already aware of)
Photo #2:
The B&W is a good
idea in theory, but in caves, it just seems to make the photo seem "drab", especially if you use "hard light" like you did in this shot... It also makes the shadow too crisp, which detracts from the main photographic subjects, IE, Model and formation. TIP: for doing B&W in caves try using heavy diffusion on your flash. It will help with the shadow "crispness". Personally, I would have preferred to have seen this shot in color, so I could see the cave's color, as well as the color of the corset...ESPECIALLY if the color in the formation and the color of the corset "matched" Good shot, again, but with lighting issues, and possibly in color. Try taking multiples of each shot, with different camera settings and lighting setups.
Photo #3
My only major critiques of this shot are:
It needs just a "smidgen" of front lighting on you, so you can tell your silhouette is an actual person and not just a very human like shaped formation.
The "hot spot" just behind your derriere needs to be toned down... this shot could benefit greatly from some diffusion to tone that hot spot down just a hair....Good concept overall, just needs the hot spot turned down, and the front lighting turned up.
EDIT: Another point on this photo, is, again, if I can't
see the corset, it kind of detracts from the "corset and caves" concept. This, again can be fixed with slight front lighting.
Photo #4
First, it is B&W, so.....(You already know my standpoint on B&W, so I won't bore you with opinionated redundancy)
The biggest issue with this one is that it has no real focal point...You are too far away from the formation to portray the idea.....I would have moved the camera a little closer to the subjects, and moved the "model" closer to the formation...that way you can more clearly see that the "model" is intently looking at the formation.... Please don't take this wrong, but it is plain. It makes me think "OK, so there's a girl in a cave..wearing a dress and a corset..huh".....It just lacks the certain element that separates a "picture" from a "Photograph"
All in all, you have the right idea, you just need to work on your lighting issues..... Try diffusion, and try "light painting". If you don't want to carry a ton of kit, here's another tip: Go grab some cheap led flashlights from Lowes or any other hardware place (try different color spectrum bulbs too, IE: yellow, white, and blue spectrums), and set them up for lighting...here's are a couple of examples of what you can do with some cheap LED flashlights, some diffusers, and a prolonged exposure.:
REMEMBER, there is NOTHING that says your lighting HAS to come from a FLASH!!!! Hope this helps!!
Cheers, and keep shooting!!!
